FAN.

SPECIFICATION forming part of Letters Patent No. 780,688, dated January24, 1905.

Application filed May 19, 1904. Serial No. 208,643. I

. To all whom it may concern:

Be it known that I, MAX A. SKALL, a citizen of the United States,residing in New York, borough of Manhattan, in the State of New York,have invented certain new and useful Improvements in Fans, of which thefollowing is a specification.

This invention relates to an improved fan of that type in which analternating rotary mo' tion can be imparted to the handle or support ofthe fan, so that the fan-body is moved without the usual vibrating orto-and-fro motion; and for this purpose the invention consists of a fanthe body of which is provided with a short stem attached in a socket,which latter is swiveled on the handle of the fan and pro vided with apinion to which alternating rotary motion is imparted by a segmentsupported at the upper end of a motor-spring, the coiled lower end ofsaid spring being firmly secured in the lower end of the handle, whilethe upper curved end is provided at its outermost end with a stop forlimiting the movement of said segment.

The invention consists, further, of means for holding the toothedsegment on the upper end of the motor-spring in mesh with themotiontransmitting pinion on the stem -engaging socket of the fan-body,as will be fully described hereinafter, and finally pointed out in theclaims.

In the accompanying drawings,Figure 1 represents a front elevation of myimproved fan. Fig. 2 is a side elevation of the same. Fig. 3 is 'avertical transverse section on a larger scale and showing the connectionof the fan-bodywith the handle and the mechanism for imparting motion tothe fan; and Fig. 4: is a detail horizontal section on line 4 l, Fig. 3.

Similar letters of reference indicate corresponding parts.

Referring to the drawings, Adesignates the body of thefan, which is madeof any suitable material, form, and design. To the lower'part of thefan-body A is attached a short stem B,

which is secured into a socket G, the latter being connected at itslower end by a screwspin'dle D to the handle H, so as to form a swiveledconnection therewith, as shown clearly in Fig. 3. On the contracted end0 of per end of a motor-spring M, which is made,

preferably, of stout spring-wire, the lower end of the spring being bentinto a coil m, that is inserted into a recess of the handle H, the endof said coil being extended in upward direction and driven into a borein the lower end 171/ of the handle in order to insure the rigid.

connection between the motor-spring and the handle. For retaining themotor-spring in the lower recessed end of the handle a transverse pin orbrad m is forced through the end of the handle and coil, as shown inFigs. 1 and 2. The end of the curved upper portion of themotor-spring'M'is bent downwardly, so as to form a stop m by which themotor-spring is held in a normal position of rest, as shown in Fig. 1.This downwardly-bent stop of abuts againsta projection m on the upperpart of the socket of the handle H, as shown in Fig. 4. The toothedsegment or rack f is held in mesh with the pinion by means of aguidepiece g, which is riveted or otherwise attached to the socket atthe upper end of the handle, said guide-piece preventing any lostlateral motion of the segmentalrack f, so that during the forward andbackward movement it is held in mesh with the pinion, while its stop malways strikes against the abutment m when the segment is returned bythe coiled end m of the motor-spring in into its normal position,

as shown in Fig. 1.

In using the fan the handle is taken hold of by the fingers, while thethumb is placed against the inclined arm of the motor-spring M, which'is pressed toward the handle, so that the movement of the segmentalrack imparts rotary motion to the stem, and thereby to the fan-body. Byrelaxing the pressure of the thumb on the inclined arm of themotor-spring the same moves back again until the stop m is arrested bythe abutment'm, the return motion of the segmental rack imparting motionin opposite direction to the fan-body, and so on alternately by thepressure of the thumb on and release of the thumb from the arm of themotor-spring, whereby an effective alternating rotary motion is impartedto the fan-body and a ventilating action is produced.

The improved fan has the advantage that it is very durable, inasmuch asa motor-spring of the type employed in its construction has been foundto be of suflieient power to operate the fan for a great length of timebefore wearing out.

The device can be cheaply manufactured and as the operative partsthereof are all exposed to view can be readily repaired in case ofbreakage.

Having thus described my invention, I claim as new and desire to'secureby Letters Patent- 1. The combination, with a fan-body and its stem, ofa handle in which said stem is rotatable, a pinion connected to saidstem, a rack engaging said pinion, and a downwardly-extendingmotor-spring connected at one end to said rack and at the other end tosaid handle.

2. The combination, with a fan-body provided with a stem, of a handle, asocket engaging'said stem and having a swiveled eonnection with saidhandle, a pinion on said socket, a segmented rack meshing with saidpinion, and a motor-spring having the upper end connected to said rackand the lower end secured to the lower end of said handle.

3. The combination, with a fan-body provided with a stem, of a handle, aswiveled connection between the stem and handle, a pinion on saidconnection, a segmental rack meshing with the pinion, a motor-springattached at its upper end to the segmental rack and having its lower endseated in a recess at the lower end of the handle, and a stop device forarresting the outward motion of the segmental rack and the motor-spring.

4E. The combination, with a fan-body having a stem, of a handle, asocket engaging said stem and having a swiveled connection with saidhandle, a pinion on said socket, a segmental rack meshing with saidpinion, a guide-piece on the handle for holding the segmental rack inmesh with the pinion, a motorspring provided with a bent upperportionattached to the segmental rack and having its lower end secured to theend of said handle, and a stop device for the segmental rack at theupper end of said handle.

In testimony that 1 -claim the foregoing as my invention I have signedmy name in presence of two subscribing witnesses,

MAX A. SKALL.
